Notes

For softer texture, use very ripe bananas and avoid overbaking. For crispier topping, chill streusel before baking. Freeze wrapped slices up to two months. Chill before slicing for cleaner pieces. Add walnuts, chocolate chips, or nutmeg for flavor changes. Store covered two days room temperature or five days chilled.
